A The` plugl 19 lf's Vbored#axially to have the., oentralboreor passage 23 discha'rgingfroiiifv f theforward lend-'of the plug-19' through* ,the Washer20and intothe tip-13'. A,passageway*V 24 is formedf to extendthroughone, side'of niol is a second passageway 25 throughone side of the plug 19 discharging'into the bore 23, which passageway 25 may be brought to communicate with the passage 16 upon rotating the screw 22 in a counter-cloekwise direction as viewed from the collar end of the head 10.

The plug 19 has an annular groove 26 formed around it along a length Yremoved from its inner end to provide a space into,V

which all of the passages lmaydischarge. A longitudinal slot`27 is cut along a sidefof the plug 19 inthe same planeas that vof the passageway 24 but on the opposite side therefrom, and continues from .the groove 26 back to and over the orifice of the drainage passage 17. A second slot 23y is cut longitudinally along the side of the plug 19 on the same rsiideand in the same plane-as that of the passageway 25to providea passageway fromthe groove 26. The outer end ofthe slot 28' terminates in the same transverse,

' plane as thatof the end of the slot 27 sageway 25 around to registerwith the pas-V sage 1,6, the iui'd -may Vstill continue to flow from 'fthe passage 16 into the/plug bore 23 and out the tip 13 buty theQslot '2 7 has been removed-from communication withthe drainage passage 17 and no discharge ofthe iiuid is to be had from the groove 26.k By revolv.-V ingthe screwz22-anoth-er ninetyk degrees, in the same direction, the passagewayy 25 is re*- moved from registry with the passage 16 and no fluid may then flow into the bore 23. The slot 28thas 4also been revolved, but no drainage mayoccur, thehiiuid still remaining inthe cavity without further supply v thereto or drainage therefrom.

Another. ninety degree .rotation of theV screw '22 brings theslot 28 around to com-- municate with the passage 17 and thereby permit drainage therethrough, without any iiuid from the. passage 16 entering theplug bore23. .Further rotation of the plug 19 brings the passageway 24 back to the original position. The plug 19 Ymay of course berotated in either directionto any position to secure the ow desired. I

.. Referring to Figs. and 6, the valve plug 19 corresponds to the valve plug 19 in'all respects withg the exception that no annular groove 26 is formed thereon and theslots 27 slots 2,7 and 28 whereby 4the slots may regis- Y ter Vwith the passages in the head 10.

carried in the vbore'32, and has passageways and 36 in the same transverse plane one lentering'the side of the plug at ninety degrees .from the other `,to discharge into the central longitudinal bore 37 of the plug. In the samelongitudinalplane of the Ypassage- Way 35 Vis a longitudinal'slot V38 alongthe outer sideoffthe plug-34 having-a length `adapted to extend Yover the orifice of the discharge or drainage passage 33 and also over the orice of the passage 39 Vwhich extends diagonallyfrom the outside near the front of the plug to dischargeinto the bore 37 at a point forward .of both2 oriices of the passage`s31 andv 33. 1 The orificesofpassages 31,1,.335and 39 are in the same longitudinal plane.: `The forward vend of the bore 37 may discharge throughfthe end-ofthe head 30. A longitudinal slotU40is cut on the sideof the zplug '34 inA the lplane of the passageway 36 with its ylength equal to that of the slot 38,y to have its ends'terminate in the same plane therewith,v l l I In the'fform shown -in Figs. 7 and. 8the plug30 isshown'as positionedl to permit a fluid flow from the passage 31, through the passageway 35,andthe v bore 37, out the -frontfendof the head 30. `At the same time drainage is .had through the passage 39, the slot` 38, andout the passage 33. l

v`'Revolving the p lug34 ninety degrees to.

bring the passageway36 to register Withithepassage 31 permits a fluid flow from the vpassage 31, th-roughy'the passageway 36, the bore 37 'and out the,front end of the head `30. No drainage is had since the singleslot 38 is removed from the passage 33. `A further ninety. degree rotation of the plug 34'brings the plug 34 around to close off both intake and drainage passages 31 and 33. The next ninety degree rotation brings the slot 40 around lto provide communicationbetween the passage 39v and the drainage passage 33,.

topermit .drainagel without inflow of liiuid from the passage l31. It is'to be notedhthat, since thepassageway 36 has the slot 40' pass# ing overits outer end, drainage may'also be had from through the front end of the bore-37, out the passageway 36, 'through the.

slot 40, and out the passage 33. The next ninety degree rotation returns the plug 34 While I have herel shown .and described my invention in minute detail, it is .obvious i, to the osition asiindicated in Fi s. 7 and 8."
